If they do allow Novians to result from scrapping buildings on plots, the next thing you are going to see is people going around, buying all the unowned plots with buildings left on them, scrapping the entire plot for the Novians, then selling the plot back to the community manager. Lather, Rinse, Repeat.

Oh, and 24 projects on Order is NOT a good justification for Novians. I don't want to see all those projects done in a couple days, leaving us nothing to do for months, and cheating the rest of the builders who wanted to participate, but are too new to have Novians stockpiled a chance to contribute. To me, it feels like cheating, probably because it is.

Now, they could make an irrational game mechanic that prevents you from using Novians on community projects, but it still won't solve the first problem where people buy up plots and raze entire communities to the ground just to greedily stockpile Novians.
